-Goal: restores O2 supply/demand balance to the heart by: 

1. Dilating vessel-Increasing the supply of O2 to heart.

2. Increases workload of heart- Decrease heart's demand for O2.

3. Drugs used one: Nitrates, beta blockers, Calcium channel blockers

Anti-Anginal Agents:

Prototype: ____

Anti-Anginal Agents:

Nitrates

Prototype: Nitroglycerin (Nitro-stat)

Indications (1):
